+## Allocate resources (make credentials)
+
+Follow [installation instruction](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-linux?pivots=apt)
+for Azure CLI `az`. [Login](https://learn.microsoft.com/en-us/cli/azure/authenticate-azure-cli) for managing resources:
+
+```commandline
+$ az login
+```
+
+Steps below follows [HOWTO](https://learn.microsoft.com/en-us/azure/virtual-machines/linux/build-image-with-packer).
+Create group as container for result image. Value `packer` is from property `managed_image_resource_group_name` of
+`azure-arm` packer's builder. Value `eastus` is property `location` of `azure-arm` (Azure has two kind notation for
+the same location).
+
+```commandline
+$ az group create -n packer -l eastus
+```
+
+Packer allocates resources on its own. It requires access to subscription. Obtain id.
+
+```commandline
+$ az account show --query "{ subscription_id: id }"
+{
+  "subscription_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx"
+}
+```
+
+Create credentials for packer.
+
+```commandline
+$ az ad sp create-for-rbac --role Contributor --scopes /subscriptions/<subscription_id> --query "{ client_id: appId, client_secret: password, tenant_id: tenant }"
+{
+    "client_id": "f5b6a5cf-fbdf-4a9f-b3b8-3c2cd00225a4",
+    "client_secret": "0e760437-bf34-4aad-9f8d-870be799c55d",
+    "tenant_id": "72f988bf-86f1-41af-91ab-2d7cd011db47"
+}
+```
+
+Set environment variables.
